在Mac中安装Homebrew

Question

我正在尝试使用以下方法在Mac v 10.12.2中安装Homebrew

brew install node

但是我得到了这些错误：

Answer 1

1-首先，安装Homebrew。

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2-然后运行brew更新，以确保Homebrew是最新的。

brew update

3-作为一种安全措施，应运行冲煮医生以确保系统可以冲煮。运行以下命令，并遵循Brew医生的任何建议。

brew doctor

4-下一步，将Homebrew的位置添加到.bash_profile或.zshrc文件中的$ PATH中。

export PATH="/usr/local/bin:$PATH"

5-下一步，安装节点（npm将与节点一起安装）：

brew install node

6-要测试您的Node和npm安装，请尝试安装Grunt（可能会要求您使用sudo运行）：

npm install -g grunt-cli
